Genetic variability of phosphate solubilizing activity by monocaryotic and dicaryotic mycelia of the ectomycorrhizal fungus Laccaria bicolor (Maire) P.D. Orton

Homocaryotic mycelia obtained from spores of Laccaria bicolor S238 have been compared in vitro for their efficiency in solubilizing poorly soluble phosphates. This could lead to genetic selection according to such criteria. However, there is very little room for improvement as the wild strain was shown to be one of the most efficient solubilizers among the strains tested. Twenty dicaryotic strains obtained by crossing the compatible homocaryons...
